A61h 11/00 U.S. Cl. 12852 3 Claims ABSTRACT OFTHE DISCLOSURE A multi-speed portable hair shampooer operated by aself-contained rechargable battery, and having a detachable scrubberhead. The scrubber head is mounted on the end of a reciprocating shaft.The reciprocating shaft is supported by a plurality of rollers. A casingis provided for housing the various elements and in use, the casing isheld in the hand while applying the scrubber head to the scalp.

BACKGROUND OF THE INVENTION This invention relates to shampooersgenerally, and more particularly to a portable battery operated hairshampooer suitable for either home or professional use. Scrubbing thescalp and hair during a shampoo has remained a manual operation, becauseof the danger inherent in using a shampooer operated on the customary110 volt electrical supply available in most homes and beauty salons.However, with the introduction of high capacity, low voltage rechargablebatteries, electrical appliances may now be designed for use in andaround water without fear of severe shock or electrocution.

SUMMARY OF THE INVENTION This invention comprises a portable hairshampooer having a scrubber head detachably mounted on a reciprocableshaft extending from a waterproof case. The reciprocable shaft is driventhrough a Worm and spur gear assembly by an electric motor receivingpower from a self-contained rechargable battery. The shampooer is storedon a charger stand which is connectable to a source of electricalpotential by means of an extension cord.

3,511,229 Patented May 12, 1970 For structural details of the invention,reference is made to the drawing in which numeral 10 designates awaterproof case having a removable cover 12, with a gasket 13therearound and attached by screws 14. A shaft 16 is supported in thecase 10 for reciprocal movement between spaced rollers 18. The shaft 16extends from one end of the case 10 through a sealing grommet 20, and isprovided with a terminal section 22 disposed at approximately degrees tothe longitudinal axis of the shaft 16.

A scrubber head 24 is removably threaded on the end of the terminalsection 22 of the shaft 16. The inner end of the shaft 16 is operativelyattached by a connecting rod 26 to a rotatable spur gear 28. A wormdrive gear 30, engaged with the spur gear 28, is mounted on the shaft 32of a multi-speed direct motor 34. A control switch 36 for the directcurrent motor 28, has a selector button 38 slidably seated on the case10.

A rechargable battery 40, preferably of the nickel cadmium type, foroperating the direct current motor 34, is mounted in the case 10. A pairof spaced insulated terminals 42, for connection to the battery 40 areprovided in a protective recess 44 at one end of the case 10. A chargerstand 46, for the case 10, has an electrical cord 48 with a plug 50thereon for connection into an electrical outlet not here shown. Thecharger stand 46 provides a pocket 50 for holdably receiving the case 10and supporting it in an upright position as shown in FIG. 1.

A two pole electrical outlet 52 in the pocket 50' of the charger stand46 is adapted to receive the two spaced insulated terminals 42 in theprotective recess 44 when the case 10 is resting on the charger stand46. In practice, a variety of scrubber heads 24 may be provided for usewith the applicants shampooer so that it may be readily adapted to meetthe individual requirements of each user.

ELECTRICAL CIRCUITRY As shown by the schematic diagram of FIG. 8, themulti-speed direct current electrical motor 34 is connected to therechargable battery 40 through the control switch 36. The control switch36 has three current limiting resistors 54, 56 and 58, each providing adifferent operating speed for the electrical motor 34. The spacedinsulated terminals 42 in the case 10 are connected one to each pole ofthe battery 40.

As shown by the schematic diagram of FIG. 9, the two pole electricaloutlet 52 in the pocket 50 of the charger base 46 is connected through asilicon diode rectifier 60 and a current limiting resistor 62 to theelectrical cord 48. A filter capacitor 64 is connected across theterminals of the two pole electrical outlet 52.

Based upon the foregoing discussion, the applicant is of the opinionthat his invention has fulfilled a long-felt need in the field ofshampooers, and that he has accordingly made a valuable contribution tothe related art. However, while the invention was described withreference to the structural details of a single embodiment, it will beappreciated by those familiar with the art that the principles involvedare susceptible of numerous other practical adaptations.

I therefore claim as new and desire to secure by Letters Patent:

1. A hair shampooer comprising a case, an electric motor in the case, abattery in the case for operating the electric motor, a spur gearmounted for rotation in the case, means for driving the spur gearoperatively con nected to the electric motor, longitudinally spacedrollers transversely mounted in the case, a shaft supported on thespaced rollers having one end projecting from the case, a rod pivotallyconnected to the other end of the Shaft, pivoted means connecting therod eccentrically to the spur gear so as to impart a reciprocatingmovement to the shaft when the electric motor is in operation, and ascrubber head on the projecting end of the shaft.

2. The hair shampooer of claim 1 having in addition a terminal sectionon the projecting end of the shaft disposed thereto at substantiallyright angles.

3. The hair shampooer of claim 2 having in addition 10 References CitedUNITED STATES PATENTS L. W. TRAPP, Primary Examiner U.S. Cl. X.R.
